When you post, people read your post and can vote in steem crypto in varying amounts depending on how their resources are and/or how much they like what you've shared.

Also, since you are already on steem, ignore my link and go to actifit.io and just log in with your posting key. My mistake for putting the link in my response to you earlier. Anyway, once you sign in and download the app which is free, to your phone, you are good to go. Let me know when you get logged in and I will send a friend request in that community to you!😇
